Useful when checking the effects of header synchs for the files it uses
as a input to generate string tables, in retrospect this is how it
should've been done from day 1, not requiring the header_dir to be set
on the Makefile, will change everything later, so that the only parm,
common to all generators will be $(srctree) and $(beauty_outdir).

So, to see what it generates, just call it without any parameters:

  $ tools/perf/trace/beauty/prctl_option.sh
  static const char *prctl_options[] = {

  [42] = "GET_THP_DISABLE",
  [45] = "SET_FP_MODE",
  [46] = "GET_FP_MODE",
  };
